Accepted name: L-isoleucine 4-hydroxylase
Reaction: L-isoleucine + 2-oxoglutarate + O2 = (4S)-4-hydroxy-L-isoleucine + succinate + CO2
Glossary: (4S)-4-hydroxy-L-isoleucine = (2S,3R,4S)-2-amino-4-hydroxy-3-methylpentanoate
Other name(s): ido (gene name)
Systematic name: L-isoleucine,2-oxoglutarate:oxygen oxidoreductase (4-hydroxylating)
Comments: The enzyme, characterized from the bacterium Bacillus thuringiensis, can also catalyse the hydroxylation of L-leucine, L-norvaline, L-norleucine, and L-allo-isoleucine, as well as the sulfoxidation of L-methionine, L-ethionine, S-methyl-L-cysteine, S-ethyl-L-cysteine, and S-allyl-L-cysteine.
